Brittle Asthma (Type 2)

ICD-10 Code
J45.901_3

Clinical Criteria for Brittle Asthma (Type 2).

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with a history of recurrent, sudden, and severe exacerbations of asthma despite optimal high-dose inhaled corticosteroid (ICS) and long-acting beta-agonist (LABA) therapy. Characterized by wide PEF variability (>40% diurnal variation) occurring over a period of at least 6 months. Patient reports frequent emergency department visits and hospitalizations due to life-threatening airway obstruction. No identifiable external triggers for recent episodes.

Clinical Examination Findings

General: Patient appears distressed, tachypneic, and uses accessory muscles for respiration. Respiratory: Auscultation reveals diffuse, high-pitched expiratory wheezing; diminished breath sounds bilaterally suggesting severe airflow limitation. Cardiovascular: Tachycardia noted; no signs of peripheral edema or jugular venous distension. Vital signs: SpO2 [Value]% on room air, RR [Value] bpm, HR [Value] bpm.

Treatment Protocol

Management plan: 1. Optimize current regimen: High-dose ICS/LABA + LAMA (Tiotropium). 2. Consider add-on therapy: Biologics (e.g., Omalizumab, Mepolizumab) if phenotype confirms Type 2 inflammation. 3. Rescue medication: SABA/Formoterol as needed. 4. Continuous monitoring: Daily PEF logging and asthma action plan review. 5. Referral: Multidisciplinary respiratory team review for potential subcutaneous terbutaline infusion or bronchial thermoplasty.
